Application filed August 3 specification.

The objects of my invention are toprode; s-1mple, ,.effic1ent and{convenient means for detach-ably mounting a thin precious metal banduponthe base metal movement ring oiymounting, and to provide simple,neat, compact, efficient; serviceable, economical and convenient meansfor attachingribbons, strapsand the like, to a watchcase.

My invention consists in the novel fea tures of construction. and in thecombination and arrangement of parts as herein set forth and claimed.

In the drawings:

F ig. 1 is afront elevation of a watchcase embodying my preferredattaching means for-ladies watches;

Fig. 2 is an edgeyiew of Fig. l,- partly in section, on the line 2-2;

:Fig. 3-isaanenlargedelevational view of one of the ribbon pins;

Fig. at is an end view thereof:

Fig. 5 is an enlarged perspective view of one of the threaded screweyes; and

Fig. 6 is a modified construction, partly in section, showing myinvention applied to a different shaped case.

In the embodiment of my invention as illustrated and which showspreferred constructions I provide a watchcase 1 comprising back 2, bezel3,,,1nove1nent ring or mounting 4 of base metal and covering band 5 ofprecious metal detachably mounted thereon. The base metal movement ring4 is provided in its ends 6 with threaded sockets 4 and the preciousmetal band 5 is provided with holes 5 adapted to register with sockets 4when said band is mounted in position upon said. movement ring. Aninternally threaded screw eye 7 and a plain screw eye 8 each having ashoulder s is provided for detachably securing the precious metal bandin. position upon the movement ring and to detachably secure ribbon stemor bar in spaced apart position from the Watch case. Said bar isprovided with threads 10, head 11 and screw-driver slot 12 at One endthereof, Said 1922. Serial No. 655,496.

threads'lO engage threads 13 of screw eye 7 as shown in Fig. l and theother end of each bar 1S held in one of the screw eyes 8. In

assembling a watchcase of this construction the preciods metal coveringband is slipped 1 into position upon the outer surface or edge ofthebase metal movement ring and each ,pair of screw eyes 7 and S areinserted through holes 5 and screwed into sockets'flr until theshouldershear firmly against said precious metal band "The back 2' and bezel 3may then be snapped into posit on in. the usual way. Each pair of screweyes 7 and S are locked into position by .screwi ngthe threads 10 intothreads 13 of bar. 9 until head 11 engages screw eye Tand the end-ofsaid bar is forced into plainscrewfeye S. When a singleribbon 14 s usedto'h'old the watchcase it may be inserted-before or after the bar isinserted in position in the screw eyes and when ribbons 14; are usedeachhaving a looped or perforatedend, bar!) is inserted through lug 7 andsaid loopyand thensecuredin holding position as be fore stated.

When it is desired to inspectthe watchcase for the purpose ofdetermining theamounts of precious metal and of base metal thereinsimply reverse the operation of assembling as above stated after whichthe parts may be reassembled as before, and when it is desired tosubstitute other ribbons for ribbons 14 merely remove bars 9 and insertother ribbons therefor when replacing said bars.

In Fig. 6 I have shown a modified construction wherein the threadedscrew eyes 7 and plain screw eyes 8 are made to conform with an octagonshaped case. Ribbon or strap bar 9 is the same as ribbon bar 9 and issimilarly removable for changing ribbons, straps and the like.

An important advantage of my invention consists in the-simple andeffioient means whereby the precious metal band 5 is securely anddetachably held or anchored upon the base metal movement ring ormounting 4: by means of the removable screw eyes 7 and 8 in which ribbonbar 9 is detachably mounted.

While I have shown my invention and the preferred way of making it, itwill be understood that it is capable of modification without departingfrom the scope or spirit thereof, as defined-in the claims.

What I claim as new and desire to secure by Letters Patent is:

1. In a watchcase, a metal movement ring having a plurality of threadedsockets therein, a thin metal covering band having a plurality of holestherethrough and mounted on said movement ring with said holes inregistry with said sockets respectively, a screw eye extending througheach of said holes and screwed into the adjacent socket and a lockingribbon bar detachably secured to each pair of screw eyes.

2. In a watchcase, a metal movement ring having a plurality of threadedsockets therein, a thin metal cover band having a plurality of holestherethrongh and mounted on said movement ring in registry with saidsockets respectively, and a screw eye extending through each of saidholes and screwed into the adjacent socket and. detachable means forlocking said. screw eyes in position.

3. In a Watchcase, a base metal movement ring having holding socketstherein, a thin precious metal covering band having holes adapted toregister with said sockets respectively, screw eyes having threadedstems extending through said thin precious metal band into said socketsrespectively, and each screw eye having a shoulder bearingagainst saidband to hold it firmly in position upon said base metal movement ring,and means for detachably locking said screw eyes in position.

4. In a watchcase, a movement ring of base metal, a thin cover band ofprecious metal. thereon, a pair of screw eyes adapted to be insertedthrough said band and screwed into said movement ring, said screw eyeseach having a shoulder adapted to bear against and hold said thin bandof precious metal in firm relation with said movement. ring and a ribbonbar detach-ably connected to said screw eye to removably hold said thinband of precious metal. in position. and to detachably support saidribbon.

5. In a watchcase, an eye mounted thereon, a threaded eye also mountedthereon, a ribbon bar having a thread near one end whereby the other endthereof will enter said eye and means whereby said bar may be rotatedfor insertion or removalfrom said eyes.

6. In a watchcase, a movement ring, a band thereon, means for detachablyholding said band in position upon said movement ring and means fordetachably locking said detachable holding means 7. In a watchcase, amovement ring of base metal and a thin cover band of precious metalmounted thereon, a plurality of screw eyes having a threaded stemadapted to eX tend through said thin precious metal band and be screwedinto said movement ring of base metal and each having a shoulder adaptedto engage and hold said band in firm relation with said ring, one ofsaid eyes having a plain or smooth hole and the other an internallythreaded hole, a pin having a head and having a thread adjacent theretoand means for screwing said bar into said internally threaded eyewhereby the other end thereof is projected and held in said plain orsmooth eye.
